U.S. markets turned modestly higher Tuesday despite a strike in Greece called to protest a new austerity budget package. Leaders of the Greek government Monday announced an agreement to cut 15,000 public jobs through attrition this year and 150,000 by 2015. Party leaders also agreed on a set of spending cuts to help Greece comply with financial mandates set by the European Union, the European Central Bank and the International Monetary Fund to allow Greece to qualify for continued international assistance. The strike is a vivid reminder that there is more work to be done. Greece has yet to reach an agreement with creditors.
